I've had this Ficus tree for some time now. The growth is a bit meek. The leafs are small, the color is not as deep green and not every branch/limb has them. If you can see on the right the other Ficus tree next to this one has excellent leafs. They are lush and deep green color.
I suspect perhaps I am doing something wrong with this tree. May be the soil isn't what it needs to be or may be something else.
Can someone help diagnose what might be wrong this this Ficus tree?
